  • KJWW Wins Engineering Award for IUB/OCA Project

BY KELLY MADSEN | IOWA ENERGY CENTER

KJWW Engineering Consultants has been selected as a second place winner of the American Society of Heating, Refrigeration, and Air-Conditioning Engineers (ASHRAE) Technology Award for their work on the Iowa Utilities Board and Office of Consumer Advocate (IUB/OCA) building in Des Moines, Iowa.

Completed in April 2011, the IUB/OCA building is the first LEED Platinum state government building in Iowa. KJWW and Berkebile Nelson Immenschuh McDowell Architects (BNIM Architects) designed the building with proven, energy-efficient methods that supported occupant comfort, indoor air quality, and energy conservation. Two of the most important aspects in the building design were innovative designs in the envelope and daylighting strategies. As part of a commitment to energy efficiency, building management planned for the Iowa Energy Center to help monitor and assess the facility’s actual energy use versus designed energy use.

“Since January 2012, Iowa Energy Center has been working with the IUB/OCA, the capitol building complex facility management team, and the building design team on collecting, monitoring, and analyzing the actual building energy use,” said Xiaohui Zhou, Iowa Energy Center’s building energy efficiency program manager. “A case study report is expected to be published in early 2014.”

Initial reports have found the building to perform at an energy use intensity (EUI) of 22.1 kBtu/sf/year without renewable energy and 18.8 with photovoltaics. This exceeds the baseline by more than 70 percent and the LEED energy model by over 30 percent.

Such energy-efficient results in the IUB/OCA project warranted the second place ASHRAE Technology Award, which recognizes outstanding achievement in the design and operation of energy efficient buildings. As a result of the award, KJWW’s work on the IUB/OCA building will be featured in the March 2014 issue of the ASHRAE Journal.
